Magnesium ingot factory generally uses two production methods to produce magnesium ingots: thermal reduction method and electrolysis method.
The thermal reduction method mainly uses the chemical substance silicon to purify magnesium metal. The raw materials used in the production process include silicon carbide, calcium oxide and pure silicon. The necessary conditions for the chemical reaction are high temperature and vacuum. At high temperatures, the temperature reaches 1100~1250 degrees Celsius. Depending on the reaction equipment required, magnesium ingot manufacturer will choose several different methods, but their principles are the same.
Pidgeon Production Method of Mg Ingot
The Pidgeon process is a relatively typical method for producing magnesium metal and most magnesium ingot factories applies. The raw materials required in this method are dolomite ore, fluorite, ferrosilicon 75 grade, coke and scarp iron. Firstly, the dolomite is shall be in qualified particle size through a crusher, sintered in a rotary kiln and cooled by a cooler. Then, grind it into powder by a ball mill and presse into balls by a ball press.
The dolomite is calcined in a rotary kiln or vertical kiln to make calcined-white. Then, mix It evenly with ferrosilicon powder and fluorite powder to form a dough. Finally, the pellets will be in a heat-resistant stainless steel reduction tank in a reduction furnace, to produce crude magnesium at 1200-1250°C and at a vacuum of 1.33Pa. After flux refining, ingot casting, surface After processing, we can obtain the finished magnesium ingot.
Magnesium Ingot Factory – AHMM
As a professional magnesium ingot factory, Anyang Highrise Metal Material Co., Ltd. always focus on the quality and stable supply to the customers. We adhere to the concept of quality first and pay close attention to raw material selection, production safety, equipment update and environmental protection. At the forefront of the industry. After years of technological improvements, we can now stably supply more than 5,000 tons of Magnesium ingot per year.
Electrolysis Method Production of Magnesium Ingot
The electrolysis method converts magnesium chloride solution into metallic magnesium through electrolysis. First, chlorinate the magnesium oxide is to form magnesium chloride. Then, magnesium chloride dissolve in water to form a magnesium chloride solution. Next, the magnesium chloride solution is electrolyzed, the magnesium chloride is reduced to metallic magnesium. Finally, the colletct the generated metallic magnesium, refine and purify it to obtain magnesium ingots.
